"It's really blue, this blue sun is really the first time I've seen it!"

"It's weird!"

"Blue Sun!"

"555 It's night on my side, I can't see the sun, I want to see the blue sun!"

"Me too!"

……

Other landing astronauts who were able to see the sun also looked at the sky, and the sun, which was dazzling on Earth and could not be viewed directly with the naked eye, came to Mars, because it was farther away than the Earth, and it was filtered through the helmet mirror of the spacesuit.

The sun on Mars is actually blue, not all blue, but this blue sun is still very attractive, and it is not visible on the earth at all.

"The atmosphere of Mars is thin, there are more and more dust particles and larger, mainly Mir scattering, scattering red light with the same wavelength as its own particles, and the red part of the sunlight in the direction of the line of sight is scattered, so the sun seen will be blue."

Scientists on the "Zheng He" who also got the image quickly analyzed the reason, that is, the dust particles in the atmosphere of Mars are many and large, which will scatter the red part of the sun's rays, and it will be blue in everyone's eyes, which is the same principle as the rainbow on the earth, that is, the scattering of light.

"Don't make a fuss, this is the scattering of light, don't make a fuss when you go to other alien planets in the future to see any purple, green, and cyan sun, otherwise be careful to be said to be dirt buns!"

"I thought there was something special, it turned out to be a simple scattering of sunlight, which made me happy in vain, thinking that I had discovered a new world!" The first person to discover that the sun was blue on Mars muttered.

"Haha, the climate of each planet is different, in the future, if we transform Mars and increase precipitation to return the dust particles of Mars to the ground in the form of rain, this Mars will see the sun no different from the earth!"

……

"Hurry up and work, the weather on Mars is changeable, be careful not to get too far away from the shuttle!" Jiang Zhipeng smiled and watched everyone discuss the matter of the blue sun of Mars with each other, this kind of discovery of novelty, and then everyone studied this novelty together, and the feeling of finding the answer was really wonderful!

"Roger!" "Roger!"

On Mars, Space Shuttle 1 is a large space shuttle responsible for an area that scientists have speculated to contain mineral deposits based on remote sensing satellite detections, and this area is named Area 1.

After the huge space shuttle slowly landed, the huge belly slowly opened, and the specially made Mars landing rovers slowly deployed, followed by more than a dozen astronauts wearing spacesuits.

These Mars landing rovers are also very huge, huge tires will crush the red rusty iron oxide gravel on Mars, Mars is full of this kind of sand dunes, gravel, because of the oxidation, the entire surface of Mars is orange.

Barren, dry, cold, desert, gravel make up everything on Mars now, and the occasional super storm that blows, bringing up rolling dust, sand and gravel, galloping on the unobstructed surface of Mars, especially the new Great Plains of the Northern Hemisphere of Mars, big storms are all too common!

"Bang~~" The astronauts who have begun to work will drive the large machine not too far from the space shuttle, and the huge drilling machine will start working, and the drilling rig erected high will drill down quickly, even the hardest rock can not stop the slightest.

The soil and rocks brought out are constantly packed into standard small boxes by the astronauts on the side, and labeled according to the current drilling depth, so that scientists can analyze the soil and determine the distribution of underground resources.

You can also infer the age of Mars and the history of Mars according to the radioactive materials in the soil and rocks, including whether there was life on Mars, whether there was a lot of water resources under Mars, etc., to study the history of a planet, the deep soil is the best recorder, which contains all the mysteries of Mars.

Compared with the direct and simple piling drilling and sampling in the No. 1 area, the landing space shuttle of the North and South Pole crowns is not so easy, and the No. 5 space shuttle is responsible for the exploration mission of the Antarctic crown.

Compared to other areas, it is even colder, reaching more than minus 120 degrees, and in such cold weather, ordinary steel will be frozen as brittle as ice, and it will break if you move casually.

And this is the ice, and the main component of the ice is carbon dioxide, so the shuttle in Area 5 is a small space shuttle, which does not carry large instruments and does not have a large mass.

But even so, you still have to be careful to find a place to park, land in a rocky place, be careful, the space shuttle is always on, to ensure the temperature of the engine,

The astronauts in charge of exploration here are also careful, the shoes they wear are specially made, there is a special non-slip design, and the drilling tools are not the rough tools in other areas.

A long wire connected to the energy source on the shuttle, and a heated drill bit at the other end, and the heat quickly melted the hard ice here, bringing up a cloud of mist, which was already heated carbon dioxide and a small amount of water vapor.

Because the weather here is so cold, it is necessary to pull the drill bit up from time to time, one is to collect and sample the soil and other soil carried by the drill bit, and on the other hand, to prevent the place that cannot be heated from being frozen.

The drill bit went up and down, and soon opened a hole in the hard ice, bringing up the deep soil, rocks, etc., which were collected by the astronauts on the side.

At the same time, the "Zheng He" in Mars and other scientists on Earth are also paying attention to the drilling activities in 10 places, and many things can be analyzed through videos and images.

"This Mars is really barren enough! Based on the dirt and rocks that have been dug up so far, the resources of this Mars are not as good as those of the Moon! Scientists have lamented that Mars is really a big looking thing, but there are few resources, or the distribution of Mars resources is too scattered to form large-scale minerals like the earth and the moon, and it is very troublesome to mine.

If you want to talk about the content, how big is the content of various elements on a planet must be very huge, as far as the iron is concerned, the surface of this Mars is full of iron oxide gravel and soil, but these do not have the value of mining, it is better to go to the asteroid belt and directly pull an asteroid with high iron content.

In the No. 1 area of "Keng~", the machine in charge of drilling suddenly made a huge sonorous sound, which is very unusual, you must know that this drill bit uses a variety of high-tech technologies.

The material of the drill bit is specially made by the material department, and the hardness is more than 300, and after the opening of the blade, cutting steel is like cutting tofu, even the hardest diamond in nature can be cut easily, and now it has encountered something that can block it.

"Guys, I've made a new discovery here, and there's something that can stop the drill!" The astronauts in charge of the drill bit in Area 1 rushed to the command center here.

"What is the depth of drilling?" Hearing that there was a new discovery, Jiang Zhipeng hurriedly asked.

"52 meters!"

"Send 10 more large space shuttles over and turn that area over, make sure to find this kind of thing!" Jiang Zhipeng was already excited at this time, he knew too well that the materials that could block the drill bit, not to mention nature, even man-made materials, this thing was too valuable for research.

If it is a product of nature, then what will this product be? What kind of role does it do? The discovery of a new type of material has an unparalleled impact on technology and industry.

If it's not a product of nature, it's man-made, then it's even more exciting!

Either way, it was very attractive, and even Liu Qingquan, who was far away on the earth, was alarmed, and rushed to the Academy of Sciences to watch the excavation and see what it was!

Ten large space shuttles took off from the "Zheng He", carrying various large excavation machines, which can dig out a mountain in a very short time, at a depth of 53 meters, without any problems at all.

The 10 shuttles each found a place to stop, their huge bellies opened, and large mining and excavation machines began to work.

The huge excavator can directly grab more than a dozen tons of soil with one claw; Huge forklifts are constantly digging a huge pit; Large dirt trucks are constantly transporting excess dirt to nearby places, where astronauts drive machines to rummage through the dirt.

After more than an hour, the depth of the excavation is almost close to the exploration area, at this time, all the excavated soil is carefully filtered and checked, and the suspicious objects are selected by brushing, and the boxes are packed and sealed.

"This stone is suspicious, pack it up!" The astronauts packed all the things they thought were suspicious, and at this time, they were all in the spirit of "I'd rather kill by mistake than let go!" If it weren't for the fact that there was so much dirt turned out, scientists would even want to take everything back into space.

"There's a new discovery, let's take a look, what is this?" An astronaut looked at a corner of black hedron peeking out of the dirt and hurriedly shouted loudly.

Another astronaut next to him motioned for him to set the machine, and then he walked over and slowly opened it with his hands, and a black spar the size of a watermelon was slowly revealed, this black spar was very dark, and there was no trace of reflection in the sunlight, obviously the light absorption effect was very good.

"I've made a new discovery here, too!"

"I found a black hedron here!"

This kind of black spar was also found in several other places where the dirt was brushed, and soon as the excavation deepened, more and more black spars were found, what are these black spars? (To be continued.) )
